Receiving
Your radio can be programmed to work, channel by channel, in “Open traffic” or “GROUP MODE
(CTCSS/DCS)”. Group mode prevents other users of a channel from being heard on your radio. See
“Setting Group Mode Codes” for programming instructions.
•
OPEN TRAFFIC: in this case you will hear all communication which will be transmitted on the
selected channel. When a message is received your squelch will un-mute, you will see the status LED
glowing green and you will hear the message.
•
GROUP MODE:
• CTCSS/DCS (Continuous Tone Code Squelch System / Digital Coded Squelch): are systems
which use particular TX signaling as an access “key” to work a repeater (encoder) or to unlock the
party’s signaling sensitive squelch. This last condition allows more radio networks to share the
same frequency. In this case you will receive only messages coming from parties sending a
proper TX signaling. During “CTCSS/DCS” operation, the radio may be set-up so that the
appropriate CTCSS/DCS decoder enables the speaker.
, CTCSS/DCS If more than one station is transmitting at the same time, this will cause
interference! Do not transmit if the status LED is glowing. Wait until the channel is clear before
transmitting.

70-440 User manual
Monitor Button
The Monitor button can enable or disable “GROUP MODE (CTCSS/DCS)” if programmed for that channel.
1) To enable “GROUP MODE”. Press and release the“MON” button: “SAT” icon is displayed. A Sub
Audible Tone mutes your speaker.
2) To Disable “GROUP MODE”. Press the “MON” button: “SAT” icon is not displayed. You are now
working in “Open Traffic”.
NOTE: if “SAT” icon is never displayed, “CTCSS/DCS” tone is not programmed. “GROUP
MODE” function is not available.
3) Press and Hold “MON” button for three seconds, internal squelch will be disabled and your speaker is
un-muted. Press and release the “MON” button to restore the squelch to normal operating condition.
Transmitting
1) Ensure that the channel is not busy otherwise you will create interference.
2) Press the “PTT” button, the status LED will glow red.
3) Start talking at a normal voice level at approximately 2.5 inches from the microphone (keep the
“PTT” button pressed).
4) When you have finished talking, release the “PTT” button.
Do not shout! It will not increase the distance you can transmit, but rather will make you heard
distorted.
Do not release the “PTT” button before your message is over or start talking before pressing
“PTT”, otherwise your message will be “chopped”.
A handheld radio does not allow you to talk and receive simultaneously, for this reason make your
messages short. When you are talking the other parties can not use the channel! Use common
sense.
Your radio is programmed with a timeout timer which will automatically turn off the transmitter if
you talk longer than 90 seconds. In this case release the “PTT” and wait for few seconds, the radio
TX features will be automatically restored.
Adjusting Transmit Power
Your 70-440BP can transmit with two power levels according to the distance of your party’s station(s). We
do recommend, when possible, to use the Low power setting. This will increase the battery life and will
reduce the risk of interference with other stations not in your radio network that may be sharing the same
channel with you.
1) To change the channel's Power Output level from high (2 Watts) to Low (0.5 Watt), or vice versa,
Press and Hold “FUNC” key for about 2 seconds. A small "LOW" will appear in the lower left corner
of the display to indicate “Low Power”. High Power has no indicator.
Page. 13
70-440 User manual
If the battery icon is "blinking" (Low Battery indication), the Unit will automatically switch to Low
Power when transmitting in order to help prolong the Battery's operational life. In this case, two
short beeps will be heard when you press the “PTT” key before the radio transmits.
Scanning channels
Your 70-440BP has three types of scanning available. The most used is Normal Scan. This allows you to
scan all the channels you have designated in your scan list (see Creating Scan List). The next is scan with
a Priority channel. This scan allows you to select a channel that will be monitored more often than the
other channels while scanning (for this scan to work properly you must have at least 6 channels in the
scan list). The next scan is Dual Watch. This allows you to scan only two channels of your choice. You
must have more than one channel programmed in the scan list in order for your 70-440BP to scan them.
The advanced scan function of the radio allows optionally looking for carrier or carrier with “CTCSS” or
“DCS.”
Creating the Scan-List.
1) Scroll the channel list, channels which show the “•“ icon, are in the “SCAN” list.
2) Select the channel, which is to be added or deleted from the “Scan” list.
Adding and removing channels from the Scan list is not available during scanning.
3) Press “CALL” + “MON” button, the “•” icon will appear or disappear. (See step 1 above.)
Activating, Deactivating Normal Scan
1) Press the “CALL” button +
key. You will see the channel numbers cycling continuously.
2) To stop scanning press the “CALL” button +
key.

then press the correct buttons “CALL” button +
key.
NOTE: If the Scan List has no channels, a low tone (error beep) will be heard when the “CALL” +
key is pressed, no channel will be scrolled in the display. At least two channels must be in the
Scan List for the Unit to be put in the SCAN Mode.
When a signal is received on a channel, the radio will stop scanning and the speaker will become
un-muted. When the activity on that channel ceases, the unit will automatically resume scanning.
If CTCSS/DCS have been previously programmed, the scanning will stop only if the received
carrier has the appropriate signaling.
If “PTT” is pressed during scanning, the radio will transmit on the first vacant channel. In case of no
activity, the Unit will automatically resume scanning.
Selecting a Priority Channel
One channel can be assigned as a “Priority Channel”. The scanning will look back at the priority channel
most frequently.
Current radio version only allows for PC programming of another priority channel.

Battery Packs
Information on rechargeable batteries
• When the battery pack is new it will not provide 100% of its efficiency. To reach the full battery run
time you have to “run-in” the battery with at least 3-4 deep charging/discharging cycles. After that
it will reach its maximum capacity. Please see “Proper charging of battery packs” for further
details.
• When you properly use the battery pack, you will obtain about 400 charge/discharge cycles (300
with the optional rapid charger). The battery “run time” will progressively reduce after 2/3 of its life
(approx.).
• Rechargeable battery packs lose their charge with time if left unused (self-discharge), this is
normal. A NiMH (Nickel Metal Hydride) battery can reduce 10 to 20% of its stored energy in few
days.
Proper charging of battery packs
1) Ensure that the radio is switched off,
2) Insert the radio into the cradle as explained in the paragraph “Charging the battery pack”
3) Wait the necessary time to provide a full charge. If the pack isn’t completely discharged you will need
less than 8 hours. (Battery icon does not indicate battery charging progress.)
, Do not overcharge the battery: always remember to remove the radio after the necessary time.
, The battery charger is for indoor use only.
When possible, charge the battery only when it is fully discharged or, at least, you have used it for
the major part of the day, otherwise the battery’s “run time” could be temporarily reduced.
Do not remove the radio before the necessary time, otherwise the battery’s “run time” could be
temporarily reduced.
Page. 17
70-440 User manual
• When possible charge battery packs only when they are completely discharged, i.e. when the “low
battery” icon flashes steadily.
• Do not remove the battery from the charger before the necessary time to provide a full charge.
• Provide at least two deep charge/discharge cycles per month.
Warnings for battery and chargers use
Please use these cautions to avoid damaging battery packs or the transceiver:
, Before using the battery charger carefully read any related warning or caution.
, Do not short battery terminals: this may cause fire, burns or explosions.
, Never dispose batteries into fire they may explode causing fire, burns or explosions. Strictly
follow any disposal regulation of your Country.
, Use only authorized batteries and chargers. The use of non-authorized accessories may cause
burns, fire or explosions causing serious damages to the radio/battery or serious injuries to
people.
, Battery chargers are for indoor use only.
, Be certain that your power source matches the rating listed for the supplied battery charger
(AC Adapter). If you are not sure, check with your dealer or with your local power company.
, To avoid damaging the power cable of the battery charger, do not put anything on it or place it
where it will be walked on. Insert the plug in socket provided with earth connection.
, Avoid strong shocks. Do not use the charger if it received a strong shock, has fallen down or it
appears damaged; immediately contact an authorized service station.
, Never try to disassemble or service the charger by yourself. Always contact your local dealer
for assistance.
, To reduce the risk of electric shocks disconnect the plug before providing any cleaning or
maintenance. Grasp the plug (not the cable) to remove the plug from the socket. The use of
non-suitable extension can cause fire or electric shocks.
, Do not expose batteries directly to temperatures below -20°C (-4°F) or greater than 35°C (95°F)
during their use and do not charge them outside the range of +5 to +55°C.
